[RESOLVED] Question about variable scope

[rvpals]

Hi,

I'm a little confuse about variable scope in PHP.

I have a file "setting.php" contains a line: $tablename = 'mytable';

I have a file "utility.php" has a function:

function insertintotable($info){
$query = "INSERT INTO ".$tablename." (info) values ($info)";

}

My problem is that inside a function I could not access $tablename variable from setting.php even though I use a "include 'setting.php' in the utility.php.

After include 'setting.php', I could access $tablename variable no problem, but inside a function I can not.

How do I access $tablename inside the function?

TIA

Can you give me a example:

Should I do this:

function insertintotable($info){
$mytablename = global $tablename;
$query = "INSERT INTO ".$mytablename....;
}

[stew]

function name()
{
global $tablename;

echo $tablename; // this will now work

}
